IMPROVEMENT IN BRA NDING-STAMPS.

Specification forming part ofLetters Patent No. 187,786, dated February27, 1871; application filed J annary 18, 1877.

which form part of this specification.

My invention relates to an improvement in lettering-palettes; and itconsists in operating the slides orjaws by means of a shaft that passesthrough the handle, and which has a pinion on its upper end, forengaging with movable racks that are rigidly fastened to the jaws,whereby the jaws are moved back and forth. It further consists in thedevices that are located at the end of the handle farthest away from thejaws, whereby the jaws can be rapidly adjusted or moved more slowly, butwith greater power, all of which will be more fully describedhereinafter.

The accompanying drawings invention.

a' represents a wooden handle, which has the type-bed b rigidly securedto one end, together with the set-screw c, that moves at right angles tothe two jaws d. Through the top of the bed are made two slots, out ofline with each other, down through which project the extensions from theunder side of the jaws, which extensions are each rigidly fastened to amovable raclrbar, h, that moves back and forth in a closely-fittinggroove made in the head for that purpose. Passing through the wholelength of the handle, up into the bed, is a shaft, 9, which has a smallpinion, i, fastened to its end within the bed, and which meshes withboth racks h, for the purpose of moving the two jaws back and forth, toclamp the type that is placed between, while the set-screw c clamps themfrom the side. On the opposite end of the shaft is fastened a largethumbrepresent my stamping, stamping wheel, I, by means of which thejaws can be rapidly moved back and forth. Secured to the shaft, betweenthe end of the handle and the thumb-wheel, is a worm-wheel, n, withwhich the worm 0 engages, placed at right angles thereto, for thepurpose of operating the shaft more slowly, but with greater power. Thebearing c, in which this worm isplaced, is pivoted or otherwise fastenedbetween two ears on the ferrule u, and has a cam or other equivalentdevice, :1 placed under its inner end, for raising and lowering theworm. so as to throw it in and out ofgear with the wheel 70.

By the arrangement of parts above described the jaws can be rapidlyadjusted back and forth, or made to clamp the type with great power. Allof the operating parts are removed farthest from the fire, so that thetool-can be handled with greater ease and comfort, and great amount oftime is saved.

This tool is especially designed for handon leather, and for the use ofbook-binders. I

Having thus described my invention, I claim- 1. In a-lettering-palette,the combination of the screw 0, head 12, hollow. handle a, pinion z,racks h, jaws d, shaft g, and the thumb-wheel l, substantially asspecified.

2. A lettering-palette in which the jaws are moved back and forth bymeans of racks and pinion, substantially as described.

3. In a lettering-palette, the combination of a hollow handle, a shaftpassing therethrough, anda mechanism, substantially as described, foroperating the shaft fast or slowly, substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand this12th day of January, 1877.
